Remote sensing derived maps of tamarisk (2009) and beetle impacts (2013) along 412 km of the Colorado River in the Grand Canyon, Arizona

These data are aerial image-derived, classification maps of tamarisk (Tamarisk spp.) in the riparian zone of the Colorado River from Glen Canyon Dam to Separation Canyon, a total river distance of 412 km. The classification maps are published in GIS vector format. Two maps are published: 1) a classification of tamarisk from a 0.2 m resolution multispectral image dataset acquired in M

Simulated Soil Water Potential in National Parks and Monuments of the Southern Colorado Plateau, 1915-2099—Data

These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the Southern Colorado Plateau. SOILWAT is a daily, site-specific, multi soil-layer, ecosystem water-balance model, driven by daily meteorology, as well as site soil texture and vegetation. The sites simulated correspond with Inventory and Monitoring

Low Intensity Land-use Overlap Colorado Plateau

This dataset represents the spatial overlap in areas with present (cropland, grazing, and recreation), potential (petroleum resources), or future (population) low-intensity land-use. The final areas designated as low-intensity land-use represent low intensity relative to the range of values for that variable in this region, either present or future, and do not represent th

Watershed potential erosion rate ranking system and check-dam placement suitability data within the Southern Rockies Landscape Conservation Cooperative (SRLCC)

Using Natural Resource Conservation Service (NRCS) soil databases, topographic features derived from digital elevation models, stream networks, and regional climatic patterns, I developed a ranking system for watershed potential erosion rates and suitability for check-dam placement across the SRLCC. This ranking system serves as a first step for land managers to prioritize areas for c

Geomorphology and Campsite Data, Colorado River, Marble and Grand Canyon, Arizona

This ESRI geodatabase consists of 5 feature datsets with 23 individual polygon feature classes and two raster datasets. A master campsite polygon feature class represents the boundaries of campsites identified in the 1973, 1984, and 1991 campsite inventories of the Colorado River corridor in Grand Canyon, Arizona. The other polygon feature classes represent camp locations along the Colorado...

The influence of water temperature on salmonid recruitment and adult size in tailwaters across western North America—Data

These data were used to examine drivers behind changes in water temperature downriver of dams across the western U.S. from 1995-2015 and the influence of such changes on rainbow trout recruitment and rainbow and brown trout adult length. First, we linked reservoir storage capacity and dam size to the warmest monthly water temperature per water year (WY) to assess the influence of low storag...

Early Season Invasives Mapping 2001 - 2010, Washington County, Utah, USA

Invasive annual plants such as red brome (Bromus rubens), cheatgrass (B. tectorum), and African mustard (Malcomia africana) can have profound impacts on dryland ecosystems. Potential impacts include the alteration of fuel loads and fire regimes, as well as the competitive displacement of native plant populations. Both of these impacts can significantly degrade habitat quality fo

Undiscovered Continuous Gas Colorado Plateau

This dataset is based on U.S. Geological Survey (USGS) resource assessments for “undiscovered” gas resources, which are resources that have not yet been extensively proven by drilling (USGS 2014). Individual resource assessments describe the amount of petroleum resources in units with similar geologic features. We focused on the amount of undiscovered continuous gas beca

Environmental conditions, covariate data used in model fitting, and long-term establishment predictions from 1979 to 2016 in the Great Basin, USA

Data was collected to characterize the conditions under which sagebrush occurs after seeding and wildfire in the Great Basin, and used to parameterize models used to explore adaptive seeding approaches. Data includes plot level field data on sagebrush occurrence, density, weather, and soil moisture conditions in the year that seeding after wildfire occurred. Weather data includes both ave

County Population 2100 Baseline Scenario Colorado Plateau

Future county population was based on projections for 2100 from the Spatially Explicit Regional Growth Model (SERGoM; Theobald 2005). SERGoM simulates population based on existing patterns of growth by census block, groundwater well and road density, and transportation distance to urban areas, while constraining the pattern of development to areas outside of protected areas and urban

Vegetation and Soils Data from Grazed and Ungrazed Watersheds in the Badger Wash Study Area, Colorado, USA

In 2004 U.S. Geological Survey biologists recorded vegetation and biological soil crust (BSC) cover by species as well as measured soil stability and compaction data along 85 transects at the Badger Wash study area, approximately 10 miles northwest of Mack in western Colorado. Soil samples were collected and processed for chemistry and texture. Using analysis of variance and nonmetric multi...
